#: Search both name and description (`--search` or `-s`), just the names

#: (`--name` or `-n`), or just the descriptions (`--description` or `-d`) for

#: <text>. If <text> is flanked by slashes, it is interpreted as a regular

#: expression. Formula descriptions are cached; the cache is created on the
|
|
#: first search, making that search slower than subsequent ones.
